To determine if 1152 is a prime number or a composite number, we simply look at the factors for 1152.
If the factors of 1152 are only 1152 and 1, then we know that 1152 is a prime number. Otherwise, 1152 is a composite number.
To explain better, if 1152 is only divisible by 1 and 1152, then it is a prime number, and if 1152 is divisible by more than 1152 and 1, then it is a composite number.
The factors of 1152 are as follows:
1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 128, 144, 192, 288, 384, 576, 1152
Therefore, since 1152 is divisible by more than one and itself, the answer to the
question "Is 1152 prime or composite?" is highlighted in blue below.
composite
Is 1153 prime or composite?
